Bulk convert PNG-24 to PNG-8 files with best quality
- by Gavin
Hi,
Can anybody recommend a good method of bulk converting a large amount of PNG-24 files to PNG-8 with as little loss of quality as possible and maintaining transparency?
I've tried ImageMagick but the resulting images weren't quite as crisp quality as I'd like. Using Paint.NET I was able to achieve far better results, but I can't bulk process with this tool as far as I know.
The settings I used with ImageMagick in case there's better options to use:
convert file.png -depth 4 file-output.png
I've also been playing with OptiPNG, but I haven't discovered a was of making sure the output images are PNG-8.
Cheers,
Gavin
